In the statistics of the units detailing the amount Households Melchizedek priesthood holder.
I think it would be more earnings included a subgroup of this value with the number of households without a priesthood holder, but some members of the family is male over 18 years.
That would allow to obtain lists of families to work more specifically with the priesthood and High Council.
The remaining families could be subdivided according to head of household: adult women, youth and children.
That would also allow the secretaries have to check listings families who may be poorly organized.

In the statistical report of "Households without a Melchizedek Priesthood holder", he'd like to know how many have males over the age of 18. Presumably this would be families where getting the male active and ordained would solve the problem, and be the focus of activation efforts.

Not much you can do about households that doesn't have a perspective elder other then making sure they have good Home Teachers.
